摘要

針對方向性凝固，本文使用錫鉛合金（Sn-15wt.%Pb）以及（Sn-37wt.%Pb）為材料，透過不同的實驗條件，研究不同之凝固模式及參數對於微結構之影響。由不同初始濃度之實驗結果可以發現，含錫濃度較高的時，硬度值較高。而在無磁場與磁鐵相吸的部分，觀察橫切面部位可以發現，由於受到磁場的影響，在施加磁鐵部位因為晶粒細化，中間晶粒尺寸較小，邊緣晶粒尺寸較大。

The tin-lead alloy (Sn-15 wt.% Pb) and (Sn-37 wt.% Pb) was used as the material to study the effects of different solidification modes and parameters on the microstructure through different experimental conditions. From the experimental results of different initial concentrations, it can be found that the hardness value is higher when the tin concentration is higher. In the portion where the magnetic field is not attracted to the magnet, it can be found that the cross-sectional area is observed. Due to the influence of the magnetic field, the grain size is small in the applied magnet portion, and the intermediate grain size is small and the edge grain size is large.
